Q: If any Muslim unknowingly conducts blasphemy (naoozubillah) against Nabi Muhammad (sallallahu alaihi wasallam) and then confesses his mistake and does taubah, in that case is he supposed to be killed? His tauba was private and nobody noticed his blasphemy but only he knows that he did something wrong, so what he should do?
A: If it was done purely in ignorance then Allah Ta`ala will forgive him. If he has committed the mistake in public then he should make taubah in public.
And Allah Ta’ala (الله تعالى) knows best.
